Air Conditioning is the control of temperature, humidity, movement and purity of air in indoor spaces. It’s a sub-discipline of Mechanical Engineering based on thermodynamics, fluid mechanics and heat transfer.
Air conditioning systems are designed to cool and dehumidify interiors by circulating cooling agents through a cycle of evaporation, compression, condensation and expansion. The resulting cooled air is then circulated by a fan into the space to be conditioned. The system will also remove from the air any micro-organisms, soot, dust and other ‘foreign bodies’ which can build up in an environment.
The most common way to cool an office or home is by using a split system air conditioner. This will consist of two units: an outdoor compressor/condenser unit and an indoor evaporator coil. The outdoor unit houses the condenser coil and compressor which are surrounded by copper tubing connected to the indoor evaporator coil. The indoor evaporator coil draws warm air over the refrigerant in the evaporator coil which evaporates, cooling and then returning to the room. The cooled air then passes over the evaporator coil and the process repeats.
In order to perform efficiently, an air conditioning system needs to be able to change the state of the refrigerant. This is done by a series of switches and relays that allow the evaporator coil to switch between liquid and gas and back again. This allows the evaporator to absorb more heat from the air and this reduces its temperature.
All modern air conditioning systems, from large commercial air conditioning units right down to the smallest window package air conditioners will use a filter to prevent dirt, dust and dander from entering the evaporator coil and blocking the flow of cool air. The filters are usually made of a gauze-like material and must be cleaned or replaced frequently in order to function correctly. Failure to replace or clean the filters can cause iced-over evaporator coils, reduced efficiency and increased electricity bills.
There are a variety of types and sizes of air conditioning systems available in the UK for commercial, industrial and domestic environments. From small window units to larger ducting installations the choice can be confusing to some, but it’s important that the correct system is chosen for your requirements.
The most popular option is a central ducted system which cools the entire house or building, however ductless mini splits and wall/window mounted units are becoming increasingly popular as they offer the same functionality in a smaller form factor that makes them easy to install in any property.
Air conditioning is a great option if you need to keep your business, workplace or household at a comfortable temperature, especially during the warmer months when opening windows and doors just won’t do the trick.
